Aircon Service

[daveandsharan]

Hi everyone, hope you can help me to verify if my aircon service was actually carried out by my main dealer.

 

I recently took my sharan in for a 60k service and a two yearly aircon service. The aircon was working although the air wasn't particularly cold.

 

When I collected my car, I couldn't feel any difference in the air temperature from the aircon. I had expected a blast of really cold air.

 

Under the bonnet, I note there are two valves associated with the aircon, both with black plastic caps plus traces of green dye. I assume this is where the technicians measure or test the refigerant , or is this where they empty it and refill it?

 

On closer inspection both valves and caps are still covered in road dust and do not appear to have been touched in ages. No fingermarks or anything.

 

Before I question the dealer I thought I would ask you people how the aircon is serviced. Should the valves and caps have been removed for the service?

 

Any help/ comments welcome

 

Thanks

The caps have to be removed to connect the equipment needed to do anything to the system.

 

A cheat would have been to remove only the low pressure cap and test one side of the pressure and top up there but that would have been a DIY rather than a proper service.

 

A proper service would remove both caps and connect their equipment, vacuum out the system, pressure test it and then refill with the correct amount of refridgerant and oil.

Many thanks Mr T,

 

I assumed that might be the case, but now you've confirmed it,.

 

Thanks again
